Final answer:
Diverticula are small sacs that develop in the weakened area of the intestinal wall. When these sacs become inflamed, it is called diverticulitis.
Step-by-step explanation:
The term that refers to the sacs that develop in the weakened area of the intestinal wall is diverticula.
Diverticula are small pouches that form in the weakened areas of the colon, most commonly in the sigmoid colon. These pouches can become inflamed and infected, leading to a condition called diverticulitis.
Diverticulitis can cause symptoms such as lower abdominal pain, fever, nausea, diarrhea or constipation, and blood in the stool. Treatment for diverticulitis typically involves antibiotics and bowel rest, and in severe cases, surgery may be required.
